Problem: On Main → Pool Devices, the member rows (nvme…p1, sdb1, sdc1) show “Unmountable: wrong or no file system.” Pools themselves are ONLINE and mounted. Sometimes the Pool Devices table goes blank until I restart emhttp.

Health checks:

• zpool status / zpool list -v: both pools ONLINE; usage correct.

• wipefs on all members: only zfs_member (no xfs/btrfs/ext4).

Tried (no data changes):

• udevadm trigger/settle

• Restart emhttp/php-fpm/nginx

• Rebuilt /var/local/emhttp/{disks.ini,var.ini} and /var/local/emhttp/pools/ (then restart)

• Stopped Docker/SMB/NFS, array stop→start

• Full reboot

• Reinstall zfs.master plugin

Your going to need to post your diagnostics for the experts to look at.

If the pools are already mounted before, they will show as unmountable in the GUI, but like mentioned, please post the diagnostics.

Type

zpool export orbit

zpool export zulu

Then

• stop the array

• start the array
